Applicator for pesticides with trigger and cartridge

A method of using an applicator,

• wherein the applicator comprises
• a housing having a first end and a second end disposed along a longitudinal axis of the housing;
• a pump enclosed by said housing;
• a handle extending from said housing;
• a cartridge having a distal end and a proximal end, wherein the cartridge is prefilled with a product which is a liquid or gel;
• a cartridge receiving port proximate said first end of said housing;
• wherein the proximal end of said cartridge is releasably attached to said cartridge receiving port along the longitudinal axis of the housing;
• an outlet formed at said second end of said housing;
• and,
• a trigger assembly housed in said handle and operatively attached to said pump,
• wherein said trigger assembly moves said pump toward said cartridge receiving port, further comprising a movable piston proximate said distal end of said cartridge, said movable piston arranged within a cavity within said cartridge, and a cap including an air vent fixedly attached to said distal end of said cartridge;
• wherein said movable piston pushes said liquid or gel product within said cartridge toward said cartridge receiving port when said liquid or gel product is pumped from said cartridge
• the method comprising
• inserting the cartridge into the cartridge receiving port of the housing;
• pulling a trigger of said trigger assembly to actuate said pump;
• drawing said product from said cartridge;
• and,
• pumping said product through said outlet.

A method of applying a product onto a target using an applicator,

• wherein the applicator comprises
• a housing having a first end and a second end disposed along a longitudinal axis of the housing;
• a pump enclosed by the housing;
• a handle extending from the housing;
• cartridge having a distal end and a proximal end, wherein the cartridge is prefilled with a product which is a liquid or gel;
• a cartridge receiving port proximate the first end;
• wherein the proximal end of said cartridge is releasably attached to said cartridge receiving port along the longitudinal axis of the housing;
• an outlet formed at said second end of said housing;
• and,
• a trigger assembly housed in said handle and operatively attached to said pump;
• wherein said trigger assembly moves said pump toward the cartridge receiving port;
• further comprising a movable piston proximate said distal end of said cartridge, said movable piston arranged within a cavity within said cartridge, and a cap including an air vent fixedly attached to said distal end of said cartridge;
• wherein said movable piston pushes said liquid or gel product within said cartridge toward said cartridge receiving port when said liquid or gel product is pumped from said cartridge
• the method comprising
• releasably attaching a cartridge onto the applicator;
• pointing the outlet of the applicator toward the target;
• pulling the trigger of the applicator;
• and,
• pumping the product through the outlet of the applicator onto the target.

An applicator comprising

• a housing having a first end and a second end;
• a pump enclosed by said housing;
• a handle extending from said housing;
• a cartridge receiving port proximate said first end of said housing;
• wherein the cartridge comprises a product in the form of a liquid or gel;
• an outlet formed at said second end of said housing;
• and,
• a trigger assembly housed in said handle and operatively attached to said pump,
• wherein said trigger assembly moves said pump toward said cartridge receiving port,
• wherein said pump is returned by a first spring,
• wherein said trigger assembly is returned by a second spring,
• wherein the first and the second springs are different springs further comprising a movable piston proximate said distal end of said cartridge, said movable piston arranged within a cavity within said cartridge, and a cap including an air vent fixedly attached to said distal end of said cartridge;
• wherein said movable piston pushes said liquid or gel product within said cartridge toward said cartridge receiving port when said liquid or gel product is pumped from said cartridge.
